As computer technology advanced, digital rendering became more realistic, and the physics models became so complex that motion-capture was no longer necessary, and the rendered actors could perform on their own. They looked better than human, acting in perfect digital sets and scenes.
Carefully groomed voice engines blended the cadence and delivery to the point where they were better than human, too.
Pretty soon, everything was digital, and fame was measured not in blocks of fifteen minutes, but clock cycles in a CPU.
No more Old Actors’ Home, just offline storage, waiting for occasional resurrection in a student director’s project.
